Photo-reactive low molecular-O-carboxymethyl chitosan (LM-O-CMCS) was synthesized by introducing a furfuryl group to the amine groups of LM-O-CMCS. The prepared photo-reactive LM-O-CMCS was characterized by FTIR, ^1H NMR, and a cross-linking test, whereas scanning Auger electron microscopy (SAM) and a MTT assay were used to confirm the cell viability. The water contact angle measurement and cell attachment test were carried out to determine the applicability of LM-O-CMCS as an anti-adhesion agent.

In previous studies, children using the community child centers reported difficulties in school adaptation. Therefore, it is necessary to study the variables related to school adaptation. The purpose of this study was to investigate the relationship between social support, self-esteem, and school adaptation of children using community child centers. In this study, we surveyed 208 children of the community child centers. The collected data were analyzed using descriptive statistical analysis, reliability analysis, t-test, one-way ANOVA, and Baron and Kenny’s three-step regression analysis using SPSS 21.0. The main analysis results showed that the self-esteem perceived by the children of the community child centers played a part of mediating role between social support and school adaptation. Based on the results of this study, the necessity of developing a program to improve social support network and self-esteem of children using the community child centers was raised. The result of the research has proven that the social support and the self-esteem are key elements on the school adjustment for the children using the community child centers. 선행연구에서 지역아동센터 이용아동은 학교적응에 어려움을 경험하는 것으로 보고되고 있어, 학교적응과 관련된 변인을 연구할 필요성이 제기된다. 본 연구는 지역아동센터 이용아동의 사회적지지, 자아존중감, 학교적응의 관계를 규명하는데 그 목적을 두었다. 본 연구는 지역아동센터 이용아동 208명을 대상으로 설문조사를 실시하였다. 수집된 자료는 SPSS 21.0을 사용하여, 기술통계 분석, 신뢰도 분석, t검정, 일원분산분석 및 Baron & Kenny의 3단계 매개회귀분석을 실시하였다. 주요 분석결과를 살펴보면, 지역아동센터 이용아동이 지각하는 자아존중감은 사회적 지지와 학교적응 사이에서 부분 매개 역할을 하는 것으로 분석되었다. 본 연구 결과를 바탕으로, 지역아동센터 이용아동의 사회적 지지망 형성 및 자아존중감 향상을 위한 프로그램 개발의 필요성이 제기되었다. 본 연구 결과는 지역아동센터 이용아동의 학교적응을 도울 수 있는 개입과 실천의 당위성을 시사 하였다는 점에서 의의가 있다

Purpose: To evaluate the benefit of colored filters in Meares-Irlen Syndrome patients with reading difficulties. Methods: Twenty-five patients were selected through a brief questionnaire aimed to determine symptoms of eyestrain or visual distortion after thorough eye examinations. The cutoff value of the questionnaire was 2.13. The rates of Korean reading and writing were measured using the RWSM (Reading Writing Speed Meter) test with and without the use of colored filters. Two months after wearing the individually prescribed colored filters, a questionnaire on the patient’s subjective satisfaction with the colored filters were completed and evaluated. Results: The blue (n = 8, 32%) and gray (n = 4, 16%) colors were the most frequently selected filters. The mean score of the questionnaire on reading difficulties was 2.72. The mean reading rate improved from 82.72 wpm (words per minute) to 101.84 wpm with the colored filters, a statistically significant change (p = 0.019). The mean writing rate did not improve. The overall satisfaction score with the colored lenses was 3.6, with the highest score given to ease of reading (4.08) and the lowest to writing (2.92). Conclusions: In cases of reading difficulty, colored filters were effective for alleviating visual symptoms and improving reading speed. It is important to achieve an adequate understanding of the specific symptoms of Meares-Irlen Syndrome and to perform a thorough eye examination to differentiate this from other ocular disorders.

Adhesions occurring on a variety tissues and operation sites are a serious side effect of surgery and may require additional surgery for removal. Therefore, Furfuryl-fish gelatin (F-f.gel) was synthesized by introducing a furan ring to fish gelatin for application as an anti-adhesion agent. F-f.gel was cured by visible-light irradiation,which changed the material from a solution to a film. The prepared F-f.gel was characterized by proton nuclear magnetic resonance spectroscopy (1H NMR), substitution ratio, gel permeation chromatography (GPC), methyl thiazolyl tetrazolium (MTT) assay, and tests for measuring photo immobilization, water contact angle (WCA), and cell attachment. The results showed that F-f.gel was effective as an anti-adhesion agent.
